Justification:Calopteryx aequabilis is common across North America and occurs in many protected areas; there is no indication of any population decline or significant threats. Hence, it is listed as Least Concern.

This northern North American species occurs from British Columbia and Northwest Territories to Newfoundland, south to California, Colorado, Illinois and New Jersey. It occurs in 10 provinces and one territory in Canada and 30 states in the United States of America.

Calopteryx aequabilis is found at clear streams of all sizes and rivers with moderate current. Can be common in places on rather tiny wooded streams, as long as there is some sun penetration. It is typically at larger streams than C. maculata, although the two occur together commonly. Also seen at rocky shores of large lakes in some areas. Larvae live among rootlets and aquatic vegetation.

The species is widespread and common and present in some federal, state, provincial, local, and/or private reserves; no further conservation measures seem to be required at this time. Considered critically imperiled in British Columbia (BC Conservation Data Centre), but Rank under review 2015; there are now four widespread localities known in the province.
